Personally, I'd pay H some attention, but show him you're your own person and you WILL have fun, with or without him -- show him what he's missing out on by not being 100% loyal to you.
As far as OW - I wouldn't be "cold" but I wouldn't be overly friendly either. If she asked about T-day, I'd say you weren't sure what the plans were yet...that you and YOUR H hadn't discussed it in detail yet...
Of course, don't take my advice because I'm in a big hole right now LOL
